摘 要: | 对内蒙古通辽玉米典型种植区现有的4种灌溉形式全生产期投入、产出和灌溉水量指标进行分析。结果表明:按照投入指标分析(仅考虑一个生产期内投资),由高到低分别为覆膜滴灌、浅埋不覆膜滴灌、低压管道输水灌溉、喷灌机喷灌;按照产出指标分析,由高到低分别为覆膜滴灌、浅埋不覆膜滴灌、喷灌机喷灌、低压管道输水灌溉;按照灌溉水量指标分析,由高到低分别为低压管道输水灌溉、喷灌机喷灌、浅埋不覆膜滴灌、覆膜滴灌。综合环境效益、经济效益和社会效益总体分析,建议内蒙古赤峰市、通辽市和兴安盟部分地区降水量为250~400mm的玉米种植区可适度推广浅埋不覆膜滴灌。

Abstract: | Based on the analysis of the input-output indexes and irrigation water consumption during a full production period of the four irrigation forms in TongLiao typical corn planting area,it is found that:in a production period,according to the analysis of in-put indexes,the order of different irrigation mode from high to low is Mulch-drip irrigation,Shallow buried no mulch drip irrigation, Low pressure pipe irrigation,and Sprinkler irrigation.According to the analysis of output indexes,the order from high to low is Mulch-drip irrigation,Shallow buried no mulch drip irrigation,Sprinkler irrigation and Low pressure pipe irrigation.According to the analysis of irrigation water consumption,the order from high to low is Low pressure pipe irrigation,Sprinkler irrigation,Shal-low buried no mulch drip irrigation,Mulch-drip irrigation.Comprehensive considering environmental,economic and social benefits, it is recommended that Shallow buried no mulch drip irrigation mode can be used in the the corn planting area with precipitation be-tween 250 to 400 mm such as ChiFeng city,TongLiao city and parts of Xing'an League in Inner Mongolia. |
